Looking for a 400ex head with valves. Anybody got one that they want to get rid of? I need one because my 440 just at a valve. The top of the piston has a hole the size of a half dollar from a valve. I had like 4-5 hours on the new motor to. When i took it apart there were two valves out. The one fell out when i took off the head, and the other was on top of the piston. Does anyone know why my two valves(opposite each other, one was intake and one was exhaust) fell out Just wondering? The other two were still in the head. Any ideas would be great and any heads for sale would be great two.
